The difference is mknbi/mkelf that come standard with etherboot when
the process the linux kernel start the kernel in 16bit mode and run
it's BIOS code,  mkelfImage  simulates the effect of the 16bit BIOS
code by reading LinuxBIOS tables or making the needed BIOS calls
itself, and then it enters Linux at it's unofficial 32bit entry
point. 

mkelfImage can take either a bzImage or a vmlinux.
